}

Constructs an Oid object from a string representation of its integer components.

Parameters:

strOid - the dot separated string representation of the oid. For instance, "1.2.840.113554.1.2.2".

Throws:

GSSException - may be thrown when the string is incorrectly formatted

exception: GSSException - may be thrown when the string is incorrectly formatted

 public Oid(InputStream derOid) throws GSSException 
{
        try {
            DerValue derVal = new DerValue(derOid);
            derEncoding = derVal.toByteArray();
            oid = derVal.getOID();
        } catch (IOException e) {
            throw new GSSException(GSSException.FAILURE,
                          "Improperly formatted ASN.1 DER encoding for Oid");
        }
}

Creates an Oid object from its ASN.1 DER encoding. This refers to the full encoding including tag and length. The structure and encoding of Oids is defined in ISOIEC-8824 and ISOIEC-8825. This method is identical in functionality to its byte array counterpart.

Parameters:

derOid - stream containing the DER encoded oid

Throws:

GSSException - may be thrown when the DER encoding does not follow the prescribed format.

exception: GSSException - may be thrown when the DER encoding does not follow the prescribed format.

 public Oid(byte[] data) throws GSSException 
{
        try {
            DerValue derVal = new DerValue(data);
            derEncoding = derVal.toByteArray();
            oid = derVal.getOID();
        } catch (IOException e) {
            throw new GSSException(GSSException.FAILURE,
                          "Improperly formatted ASN.1 DER encoding for Oid");
        }
}

Creates an Oid object from its ASN.1 DER encoding. This refers to the full encoding including tag and length. The structure and encoding of Oids is defined in ISOIEC-8824 and ISOIEC-8825. This method is identical in functionality to its InputStream conterpart.

Parameters:

data - byte array containing the DER encoded oid

Throws:

GSSException - may be thrown when the DER encoding does not follow the prescribed format.

exception: GSSException - may be thrown when the DER encoding does not follow the prescribed format.

 public boolean containedIn(Oid[] oids) 
{
        for (int i = 0; i <  oids.length; i++) {
            if (oids[i].equals(this))
                return (true);
        }
        return (false);
}

A utility method to test if this Oid value is contained within the supplied Oid array.

 public boolean equals(Object other) 
{
        //check if both reference the same object
        if (this == other)
            return (true);
        if (other instanceof Oid)
            return this.oid.equals(((Oid) other).oid);
        else if (other instanceof ObjectIdentifier)
            return this.oid.equals(other);
        else
            return false;
}

Tests if two Oid objects represent the same Object identifier value.

 public byte[] getDER() throws GSSException 
{
        if (derEncoding == null) {
            DerOutputStream dout = new DerOutputStream();
            try {
                dout.putOID(oid);
            } catch (IOException e) {
                throw new GSSException(GSSException.FAILURE, e.getMessage());
            }
            derEncoding = dout.toByteArray();
        }
        return derEncoding.clone();
}

Returns the full ASN.1 DER encoding for this oid object, which includes the tag and length.

 static Oid getInstance(String strOid) 
{
        Oid retVal = null;
        try {
            retVal =  new Oid(strOid);
        } catch (GSSException e) {
            // squelch it!
        }
        return retVal;
}

Only for calling by initializators used with declarations.

 public int hashCode() 
{
        return oid.hashCode();
}

Returns a hashcode value for this Oid.

 public String toString() 
{
        return oid.toString();
}

Returns a string representation of the oid's integer components in dot separated notation.
